Conductivities of Si thin films crystallized in solid phase with/without YSZ layers by the two-step method with pulsed laser were investigated. The temperature dependences were also measured for both undoped and P-doped films using AC Hall effect measurement. It was found that the Si/YSZ/glass structure exhibited higher conductivities than those of the Si/glass. This suggested that the Si film crystallized on the YSZ layer is more suitable for application of electronic devices, compared with the Si film on glass.
